Science
Mechanism of Action
As an amphiphilic block copolymer, Poloxamer 185 effectively lowers surface tension, allowing immiscible substances like oil and water to combine and form stable emulsions. Its surfactant properties facilitate skin cleansing by helping water bind with oils and dirt, enabling their easy removal. Additionally, it functions as a solubilizer for ingredients that typically resist dissolution, and acts as a wetting agent and conditioner, improving spreadability and texture.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded Poloxamers, including Poloxamer 185, are safe for use in cosmetics, with typical concentrations ranging from 0.005% to 20%. Due to its molecular weight and solubility, skin penetration is expected to be minimal and slow. While it may be a minimal ocular irritant, Poloxamer 185 is not considered a dermal irritant or sensitizer. Manufacturers are advised to adhere to purification procedures to ensure levels of potential by-products like 1,4-dioxane remain below established safety limits. Poloxamers are also FDA-approved for various pharmaceutical applications, indicating a high safety profile.
